the definition of the word is not actually known. the tendency of the word to be used is very frequent, however, and usually is used to break awkward silences.
Someone says something stupid...
Carrie - "Yeah Amy, turn on the air conditioner, it will defrost the windows."
(There is an awkward silence, because the last statement was incredibly brainless. Then...)
Mike - "Uhh, derp."

Ex. 1 Jennifer Lawrence is the queen of derp because of the faces she makes.
Ex. 2 "I'm bored."
"Me too."
*Awkward silence.*
"Derp."
"Yeah..."
Ex. 3 Jennifer Lawrence Queen of Derp trended on Twitter worldwide. (FACT)

A derp is a dumbass. Someone who always has a stupid look on their face. Also someone who never contributes anything of worth to anything ever. A worthless piece of shit.
